Lab-Grown Diamond Engagement Ring
Sunlight catches the sharp edges of a 4 x 4 mm square diamond, its precise geometry reflecting a quiet confidence. This semi-set engagement ring foundation in warm 18K rose gold offers a subtle glow that complements the stone’s crisp lines without overpowering them.
Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease under gloves or alongside other rings. The rose gold is hand-finished in Williamsburg, ensuring a smooth, polished surface that resists wear while highlighting the diamond’s architectural shape.
Each lab-grown diamond is chosen for clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical sourcing without compromise. This mounting invites your choice of a square-cut center stone, perfect for those drawn to modern geometry and clean edges.
Designed for those who value precision and practicality, this ring suits a range of hand sizes and styles, stacking effortlessly or standing alone with quiet strength. Resizing is available to ensure a tailored fit, crafted with care in our Brooklyn studio.
